To generate immutable Flutter models with JSON serialization, define your class fields and run Dart code generation via build_runner using the Freezed package to create type-safe data classes with automated encoding and decoding.

The best way to reduce boilerplate when creating Dart data classes is to use Freezed for immutable model generation, which automatically creates equality methods, copyWith functions, and union types without writing repetitive code.

Yes, the Freezed package supports union types for Flutter state management by enabling the creation of sealed classes, allowing you to represent distinct states like loading, success, and error within a single domain model.

You use build_runner for Dart code generation with Freezed by adding the package dependencies and executing the build runner command, which processes your annotated classes to output type-safe immutable models and JSON serialization files.

Yes, you can generate copyWith methods for domain models in Flutter by using the Freezed package, which builds type-safe immutable data classes that allow easy and safe updates to specific fields without mutating the original object.

The main limitation of using Freezed for Flutter model generation is the strict requirement for Dart code generation via build_runner, which adds an extra build step to your workflow and prevents modifying the generated files directly.
